Changing which files open in Protected View
2
2 If the red Protected View message bar appears when you open a
document, the document did not pass a validation process that
Office applies to every file you open. This can occur if the file is
damaged by a hardware or software problem or it was modified for
a malicious purpose. If the file is suspicious or unknown, the best
action is to close the document and delete it from your computer. If
you know the document’s creator, request another copy of the file.
If you decide to try to edit the document despite the warning, click
File to display the Info tab of the Backstage view, and then click Edit
Anyway.
TIP If you click Edit Anyway to open a damaged document,
the document might still fail to open. The behavior depends on
the type of damage the file has suffered.
Change the Protected View settings
1 Open the Trust Center as described in “Open the Trust Center set-
tings page” on page 382.
2 In the Trust Center dialog box, in the panel on the left, click the Pro-
tected View tab.
3 If you open document files that you download from the Internet
(including SkyDrive) only when you know that they’re safe, clear the
check box for Enable Protected View For Files Originating From The
Internet.
4 If you open document files that you receive as email attachments
only when you know that they’re safe, clear the check box for
Enable Protected View For Outlook Attachments.
5 Click OK.

TIP It’s a good idea to keep the check box selected for Enable
Protected View For Files Located In Potentially Unsafe Loca-
tions. These locations include folders, such as the Temporary Internet
Files folder, from which you can’t be sure of a file’s history.
TIP When you click the Enable Editing button on the message
bar to allow editing of a document, that document automati-
cally becomes trusted. When you open the same document in the
future, it won’t open in Protected View.
